Performance of the potentially invasive Siberian moth Dendrolimus superans sibiricus on coniferous species in Europe

AGRICULTURAL AND FOREST ENTOMOLOGY, Issue 3 2009
Natalia I. Kirichenko
Abstract 1,The native range of the Siberian moth extends from the Pacific Ocean (Russian Far East, Japan and Northern Korea) across Siberia, Northern China and Mongolia to the Ural Mountains. At the beginning of the 21st Century, this species was documented west of the Ural Mountains in the Republic of Mari El, indicating range extension toward the west. 2,The Siberian moth has recently been suggested for regulation as a quarantine pest for European and Mediterranean Plant Protection Organization member countries. However, no specific report on European host plants for this pest has been published so far. 3,In the present study, larval host plant choice and performance was tested for the first time on coniferous tree species that are widely distributed and of commercial value in Europe. 4,Based on dual-choice tests on neonates and mortality, developmental duration and relative growth rates of the first- to sixth-instar larvae, we found European larch Larix decidua to be the most suitable host for the moth larvae, whereas European black pine Pinus nigra and Scots pine Pinus sylvestris were the poorest hosts. The remaining conifer species tested, European silver fir Abies alba, Nordmann fir Abies nordmanniana, and Norway spruce Picea abies, were intermediate host plants. Douglas-fir Pseudotsuga menziesii, originating from North America, was chosen by the larvae to the same extend as European larch, and was also highly suitable for larval development. 5,If the moth is introduced to European countries, it will become damaging in stands of European larch and Douglas-fir, mixed stands of fir and spruce; however, it will be less damaging in forests dominated by two-needle pines. 6,We predict that Dendrolimus superans sibiricus will be able to survive and develop on the main European coniferous tree species, including non-native coniferous tree species, resulting in severe damage to large areas of forests.

Invasive and quarantine pests in forests in Slovakia1

EPPO BULLETIN, Issue 2 2006
Milan Zúbrik
Biological invasions of insects, plants, and fungal pest species often cause substantial disturbance to forest ecosystems and as well as severe socioeconomic impacts. Central Europe acts as a ,bridge' between Western and Eastern Europe both ecologically and as an important transit corridor for people. Human activity, including the movement of material goods, increases the risk of invasions. Some species introduced in the past have been established, becoming common and causing serious problems (such as Dreyfusia nordmannianae or Hyphantria cunea). The status, importance and spatial distribution in Slovakia of seven different forest pests recently introduced into Slovak forest ecosystems (Cameraria ohridella, Coleotechnites piceaella, Cryphonectria parasitica, Dothistroma septospora, Ips duplicatus, Parectopa robiniella, Phyllonorycter robiniellus) as well as two others not yet recorded in Slovakia (Anoplophora glabripennis, Phytophthora spp.) is discussed.

Protocols for the diagnosis of quarantine pests,

EPPO BULLETIN, Issue 3-4 2000

EPPO member countries have recognized the need for a harmonized approach to detection and identification methods for quarantine pests. In 1998, EPPO started anew project to prepare diagnostic protocols for the quarantine pests of the EPPO region. The work is conducted by the Panel on Diagnostics, which is under the authority of the Working Party on Phytosanitary Regulations. The Panel consists of 10 experts in different fields. When necessary, expert groups on specific disciplines are called upon. The Panel agreed on a suitable common format for the protocols and a procedure for producing the best quality of diagnostic protocols. As there are about 325 quarantine pests for the region (listed in the EPPO A1 and A2 lists of quarantine pests and in the Annexes of EU Directive 77/93), it was necessary to decide upon a priority list of the organisms for which protocols should be developed first. At the moment, 52 protocols are at different stages of preparation. [source]

Diagnostic protocols for organisms harmful to plants , DIAGPRO,

EPPO BULLETIN, Issue 3-4 2000
V. A. Harju
DIAGPRO is an EU-funded project to develop diagnostic protocols for 18 quarantine pests. Pilot test methods will be developed in the laboratories of the four partners in England, Scotland, The Netherlands and Spain. The methods will be ring-tested at selected EU laboratories and published on the Internet for comment. [source]

Effects of gamma irradiation on the life stages of yellow flower thrips, Frankliniella schultzei (Trybom) (Thysanoptera: Thripidae)

ANNALS OF APPLIED BIOLOGY, Issue 3 2001
JULIANA A YALEMAR
Summary Irradiation at a minimum absorbed dose of 250 Grays (Gy) has been approved by the USDA as a quarantine treatment for certain fruits in Hawaii to control four species of tephritid fruit flies. Subsequent research must determine whether this dose is sufficient to control other quarantine pests, such as mealybugs, thrips, mites, beetles, moths, and scale insects, on other commodities with export potential that are approved for irradiation treatment for fruit flies. This study demonstrated that irradiation at 250 Gy caused non-emergence of eggs and pupae, failure of larval development, and sterility of adults of yellow flower thrips, Frankliniella schultzei (Trybom). Adults were the most resistant stage tested, with 100% mortality at 57, 36 and 30 days post-treatment for the 250, 350 and 400 Gy treatments, respectively. Untreated adults survived up to 66 days. After receiving an irradiation dose of 250 Gy, no one- to two-day old eggs hatched successfully, while 3,4-day old eggs hatched but did not develop beyond the larval stage. Of the controls, 96.0% of 1,2-day old eggs and 75.9% of the 3,4-day old eggs hatched and survived through pupation. No first or second instar larvae treated with a target dose of 250 Gy were able to pupate. When pupae were irradiated at 250 Gy, 37% emerged as adults and all were sterile compared to 88.3% emergence of controls. [source]
